That's the kind of integration Sunrise is known for — it means that your Outlook calendar can fill itself with Facebook events, Evernote reminders, and Wunderlist tasks.

The basic philosophy behind the smartphone versions of Outlook is that people waste a lot of time switching between e-mail and their calendar, so why not put them in the same place? By sucking in data from outside apps, you'll have to switch even less.

Microsoft is calling this feature "Calendar Apps," with the promise that more outside services will be getting the Outlook integration treatment sooner rather than later. In a blog post, Microsoft also says Sunrise's "Connected Calendars" feature for integrating with outside calendar services like Google Calendar is coming soon.

It's all good news for users of Outlook on iOS and Android, and a further demonstration of Microsoft's newfound commitment to playing nice with the competition.
